WILLIAM WOLFE, 9F ST. LOUIS, MISSOURI.

HEEL-BUILDING MACHINE.

Application filed January 3, 1911.

To all whom it may concern:

Be it known that 1, WILLIAM lVoLrn, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Heel-Building Machines, of which'the following is a specification.

This invention relates to improvements in machines employed in building heels and, n a general way, it relates to improvements in the type of machine illustrated in Reissue Letters-Patent No. 12,483, dated January 2nd, 1906. In said prior patent I do scribed a machine in which a plurality of sectional and independently-adjustable plates was employed for causing the heel blanks to conform to the desired shape, and in conjunction with said plates, which were stationary, I employed a carrier having mounted thereon a gage against which the lifts are piled, after which operation the carrier was caused to be moved inward to force the compiled lifts between and in contact with the plates, whereupon the nail was driven and Machines constructed according to my said Re-issue Letters-Patent have gone into commercial use and have proven highly satisfactory. I have discovered, however, that the principle of operation employed in said machine is not the best for yielding the highest eiiiciency with various types and sizes of heels, and that when heels constructed of pieced lifts are to be made, there is always present the liability of the lifts becoming displaced in the movement of the carrier toward the heel former, composed of the adjustable plates referred to. Furthermore, the construction indicated necessitates the use of a relatively large number of working parts, causing the machine, as a whole, to be far more con'lplicated in construction than is desirable.

In the present. invention I aim to provide a machine which shall be relatively simple in crmstruction, and which shall be capable of equally advantageous use with all sizes and kinds of heel lifts. The present machine, while embodying certain generic features embraced in my previous invention referred to, such as the indepcndentlyadjustable plates composing the heel former, diifers radically from said prior invention in the mode of operation; and especially in the fact that I now make the heel gage relatively Specification of Letters Patent.

stationary and cause the heel'formerto advance toward and engage about the compiled lifts. By this operation, among other advantages, obviate the danger of the lifts moving or falling out of position, especially when pieced lifts are used.

The present invention also embodies nu merous features of improvement, both as to structural details and mode of operation,

which can be better understood from the detailed description to follow. I may, however, mention briefly, that the present invention embodies improved means for positively operating the heel former and nailing mechanism at appropriately-timed intervals; for

insuring an easy and accurate movement of the driving mechanism, and for insuring the proper action of the heel former without jar or danger'of buckling the lifts.

I have also illustrated in the present case a novel nail-supplying device and connecting parts by means of which it is operatively associated with the nail driving mechanism; and novel medhanism for applying paste to the heel lifts. These latter two nnproveso ments are illustrated in connection with the heel building machine for the purpose of showing the general construction and operation of the entire machine. They are not,

however, claimed specifically herein, but

form the subject-matter, respectively, of separate applications for patents. These applications are identified as follows: paste applying device, Ser. No. 675,657, filed February 5th, 1912; and nailing mechanism for heel building machines, Ser. No. 677,040, filed February 12th, 1912-.

Referring now to the drawings, 25 indicates the base or standard of the machine on top of which is mounted the frame 26, supporting the principal working parts. I 27 is the main drive shaft which is provided with the ordinary driving pullegs not shown, whereby the shaft may be con tinuousiy rotated. Mounted on the shaft 27 is a sprocket wheel 28. I i

29. indicates the mal driven shaft which has loosely mounted thereon at one end a fiy-wheel 32. Secured on the hubof said fiy-Wheel isa sprocket-wheel 30, and over this sprockebwheel and the sprocket-wheel 28 is passed a sp jocket chain 31. aeent 6 to the fiy wheel f 2 is a camgd i sk 33 having on its inner face a cam-groove 34. The camdisk 33 is keyed on the shaft 29 and is revolved at intervals under the control of the operator through the medium of a clutch mechanism, best shown in Figs. 1, 14, 15 and 16. Referring to these figures, 35 indicates a rod which is connected at its lower end to a treadle,not shown, whereby said rod may be raised when it is desired to start the machine. 36 indicates the upper member of a boxing or hearing for one end portion of the shaft 29, said member providing at one side a longitudinallyextending lug 87, which is centrally bored to provide a hearing for a rock shaft 38. 39 indicates an so arm which is secured at one end to one end of the rock shaft 38 and is curved under the shaft 29, its outer end being secured to the upper end of the rod 35. On the opposite end of the rock shaft 38 is fixedly se--8 cured at one end an arm 40, which at its outer end is inclined on one side to form a wedged portion 41 which terminates at a shoulder or stop 42.. 43 indicates a hard metal insert provided on the inner side of so the wheel 32 and surrounding the shaft 29, which insert is provided with a recess 44 for receiving the end of a sliding detent 45, which at its opposite end is provided with a lateral rectangular extension 46 which is 9-5 slidably mounted in a groove 47 formed in a hub 48 ofthe cam-disk 33, which is also provided with a circumferential groove 49, in which the tapered end of the arm '40 works. A spring 50 housed in the projection 46 .of the sliding detent, and bearing against the wall of the recess of the hub 48 in which said projection is mounted, tends normally to press the sliding detent outward so that its outer end will engage in the recess 44 of the fly wheel, which is constantly moving. When this occurs the cam-disk 33 will be caused to rotate with said fly wheel. Normally the outer end of the arm 40 rests in the groove 49, its tapered portion bear- 1 0 ing against the end of the projection 46 and holding the sliding detent withdrawn from the recess 44, and the projection 46 also bearing against the shoulder 42 of said arm 40. To place the machine in operation the 1 5 operator presses on a treadle to raise the rod. 35 which, through the medium of the arin 39, rocks the shaft 38, and thereby raises the-arm 40 to carry it out of engagement with the projection 46 of the sliding detent; whereupon the spring DU Iorces the sliding detent outward and its end will enter the recess 44 and cause the cam-disk 33 volves with the earn-disk it will be seen that as the hub reaches the completion of a single revolution the wedge shaped end of the arm 40 will engage behind the outer end of the projection 46 causing the sliding detent to be withdrawn from engagement with the recess 44, and, as the projection 46 engages the shoulder 42, stopping the operation of the machine. v

The upper portion of a vertical standard 52 of the frame is provided with a slideway 58 (Fig. 11) in which works a cross head 54 having suitably mounted thereon a roller 55 which works in a cam-groove 34 of the cam-disk 33. Pivotally mounted in I the frame '26, as indicated at 56, (Fig. 2) is a bell crank lever, one arm 57 of which passes through a slot 58, provided in the inner end of the cross-head 54, and at its end is provided with a cross-pin 59, which engages in opposite walls of a slide-box 60, which is slidably mounted in the cross-head 54. In the movement of the cam-disk the cross-head 54 will be alternately lowered and raised, while the slide-box 60 can move back and forth horizontally in said crosshead to permit the outer end of the arm 57 of the bell-crank lever to be raised and low ered.

61 indicates a ram, the rear portion of which is slidably mounted in the standard 52, and which, toward its forward end, is provided with a squared portion 62 which is bifurcated to provide a slide-way 63 for a slide-box 64.

65 indicates the arm of the bell-crank lever complemental to the arm 57, said arm 65 having its end rovided with a cross-pin 66, which engages 1n opposite walls of the slideboX 64. As the bell crank lever is rocked on its pivot 56 the arm 65 will cause the ram 61 to be carried alternately outward and inward, the slide-box 64 having a limited ver tical movement in the slide-way 63 of the ram to permit of this operation.

The forward end of the ram 61 is enlarged and formed in the shape of a cylinder, such enlarged portion being indicated by 67. The inner end portion of the cylindrical enlargement 67 is externally screw-threaded 5Q as indicated at 68, and mounted on said cylindrical portion in engagement with the screw-threads 68 is a collar 69. Slidably ,(mounted on the cylindrical portion 67 is a head 70 carrying the heel formers, and be tween the rear side of the head 70 and the collar 68 is interposed a coil spring 71. The bed 72 of the machine is provided with a stationary guide 73, having its outer edges undercut, and the head 70 is provided on its under side with a correspondingly-shaped recess to fit the guide 7 3, such dove-tail connection between the head and the guide be ing indicated at 74. Extending longitudinallv through the guide 7 3, and located centrally thereof is an aperture 15,, the inner end of which is interiorly screw-threaded to receive an adjusting screw 76. Pivotally mounted at its upper end in the forward end of the cylindrical portion 67 of the ram, as indicated at 77, is a roclnarm 78, the lower end of which, as shown by Fig. 4, is adapted to engage the end of the screw 76, the guide 73 being longitudinally grooved, as inclicated at 79, to provide space for the movement of the rock-arm as the ram is reciprocated. The upper end of the rock-arm 78 is forked to provide a yoke 80, in which yoke is pivotally supported from opposite sides a pressblock 81. The press block 81 is mounted to have vertical movement in an extension 82 forming the end of the ram 61,

o and said extension is cored out to provide an annular space surrounding the pressbloclr 81, in which space is located a coil spring 83. The-pressblock has a head 84 which receives the pressure of the spring 83. The press-block 81 is provided preferably with four vertical apertures, one of said apertures, 85, being located at the center, and the other three apertures, 86, being located near the circumference of the pressblock in such manner as to form the points of an imaginary isosceles triangle.

87 indicate spring arms which are secured at one end in grooves formed in the wall of the press block, and have their free ends bent to extend into the apertures 86, as shown clearly in Figs. 5, 6 and A similar spring arm 88 is likewise secured in a groove in the press-block, and has its free end eX- tending through a suitable channel and into the central aperture 85. The pu pose of the spring arms 87 and 88 is to retain nails, such as 8-), in their respective apertures until such time as said nails are driven into the compiled lifts.

90 indicates a heel gage upon which the lifts are piled up to the requisite height. A lip 91 projecting inward from the top of the gage prevents the top lifts from being forced over the top of the gage under the pressure of the heel former. The bottom 92 of said gage rests upon the guide 7 3 and is provided with a central hard-metal insert 93, and on its inner side with an upwardlyproje cting tongue 94.

95 indicates a casing in which is mounted a hollow plunger 96 capable of a sliding mo vee ment in'the casing 95, which is limited by means of a set-screw 97, having its end engaging in a recess 98 formed in the upper wall of the plunger. 99 indicates a washer, also mounted in the casing 95, and within the hollow plunger there is. housed a coil spring 100 which bears at one end against the closed end of the plunger 96 and at its other end against the washer 99.

101 indicates an adjusting screw which is provided with a non-circular portion 102 (see Figs. 3 and 4) so that a wrench may he applied thereto to adjust the screw to incgease or diminish the tension of the spring 1 0.

103 indicates a bolt having a non-circular end 1041, a circular shoulder 105, and beyond said shoulder a screw-threaded end 106. The adjusting screw 101, the washer 99 and the inner end of the plunger 96 are centrally apertured, and the bolt 103 extends through said apertures, and through the coil spring 100, its shoulder 105 resting against the inner end of the plunger, and its screw-threaded portion 106 being screwed into a screwthreaded aperture provided I on the front side of the gage 90.

It is contemplated that gages suitable for heels of different sizes and heights will. be interchangeably employed in connection with my machine, and .to remove one gage and replace another a wrench is applied to the end 104- of the bolt and the same is screwed out of engagement with the gage 90, the substitute gage is put into its place and the bolt turned into screw-threaded engagement therewith. The bolt 103 is capable of a sliding movement in the adjusting screw 101, and thespring 100 will normally press the plunger 90 inward a distance from the casing determined by the length of the slot 98, so that the gage 90 will offer a yielding resistance to the pressure of the heel formers' asthey are brought into contact with the compiled lifts.

The casing 95 is provided with lateral extensions 107 which are in turnprovided at their inner ends with vertically-disposed housings 108, said housings and extensions being formed integral with each other and with the casing, respectively. The housings 108 are provided with recesses having parallel walls in which are mounted a greater or less number of plates 109 in superimposed relation. Mounted in the upper ends of the housings 108 are clamping screws 110, which are provided in their outer ends with non-circular apertures 111 into which a suitably-shaped key may be inserted to turn the screws into engagement with the as sembled plates 109 to lock them securely in their adjusted positions. Projecting laterally and forwardly from opposite sides of the front end of the head 70 are.integral forked extensions 112 (see Figs. '3, 12 and 13) which provide vertically'disposed housings 113, preferably four in number, similar to the housings 108. These housings are adapted to receive a greater or less number 7 of plates 114: which are clamped to adjusted positions by means of screws 115, similar to the screws 110. By unscrewing the screws 115 the plates 114: may be adjusted in their respective housings to conform to the curvature of a templet of the size of'the heel to be made, after which the screws 115 are turned to lock the plates in their adjusted Pivotally mounted on a pin 117, secured at the bottom of the casing 95,'are arms 118 (see Fig. 8) inthe lower ends of which is mounted a bolt 110. Mounted on the bolt 119 between the arms 118 is a. cam 120, pro-. vided with a handle 121, the adjustment bein g such that by moving the handleforward or backward the said cam may be turned into or out of engagement with the under side of the frame of the machine; 13V releasing the engagement'of the cam with the frame the casing 95, and thereby the gage 90, and the plates 109, may be moved to adjusted positions relative to the-head 70 carrying the heel. forming plates 11%, and so adjusted may be rapidly clamped into position by turning the handle 121 to cause the engagement of the cam 120 with the under side of the frame, the inter-engagement of the serrations of the guide and the casing 95 justed position;

I will now proceed to describe the mechanism by means of which the assembled lifts are nailed to the heel; in the case of single lifts, by one nail, as would be the case of the heel illustrated in Fig. 12, or, in the case of pieced lifts, with three nails, as would be the case with the heel illustrated in Fig. 13.

Mounted on the forward end of the shaft 29 is a crank-disk 122, provided with a crank pin 123, on which is mounted a cross-headv assisting in holding the casing in the ad- 124- which works in a transverse slot 12 1 formed in an enlargement 125 of a vertically-movable dr1ve-bar 126 carrying in its lower enda driver 127, which 18 mounted in l a removable head 128 through the medium of a block 128 and a .washer 128 By removing the head 128, three drivers may be placed in the block if'three nails are to be driven, in the case of a heel being built up of piecedlifts, as illustrated in Fig.13. The drive-bar 126 is mounted to reciprocate in an upper bearing 129 and a lower bearing, 130, provided at the extremities of a forked eXtension 131 forming an integral part of a forward frame member 132. The frame member 132 is bifurcated and laterally extended at its lower end to provide space for the movement of the ram 61 and its head, as

indicated at 133 of Fig. 1. Referring to Fig. 17, the drive-bar 126is provided immediately above the enlargement 125 with a collar 134, and in the upper'portion of the bearing. 129, which is largerin circumference than the portion! of the drive-bar worle ing in said bearing, asleeve 135, which is held in place by a set-screw 136. Between the said sleeve and collar, and encircling the drive-bar, is interposed a coil spring 137,

the purpose of which is to act as a combined bumper and actuator. This action will more clearly appear from the description of the ogcration of the machine to be given later.

The mechanism for supplying nails to be driven into successive heel-blanks comprises the followingparts: Mounted on the rock shaft or pivot 56 of the bell crank lever 57b3, a rock-arm 138, to the outer end of which is pivotally secured one end of a link 139, the opposite end of which is pivotally secured to the bottom side of a receptacle 140 at the rear thereof. Said receptacle is providedwith a hinged door 141, by means of which nails may be supplied thereto. and its fin-ward end. along the bottom edge, is pivoted, as indicated at 142, to a stationary rare-way 143. The bottom of the receptacle 110 provided with three slots which are of a width to allow the shanks of nails to fall therethrough, but not wide enough to permit the heads to pass through. .is a result. the nails in said slots will be held in a suspended position as shown, as to one of the slots, in Fig. 19. The race-way 143 is provided with three slots 1 11, which aline with and. in efiect, form continuations of the slots in the bottom of the receptacle 140. The bottom of the race-way 1 13 is se cured to a transverse support 11-5. in which are inserted from the under side three short tubes 146. the support 145 being slotted to correspond with the slots 141, and the tubes 146 having slots in their sides, as at 147, to permit the nails to enter the same. At the bottom of each of the slots 1-14: there is secured, by. a screw 148, a spring-arm 119, which has a bent end 150 projecting into a vertical aperture 151 forming an enlarge mcnt of the bottom of the slot 1 H, said bent end being slightly below the plane of the upper side of the race-way so that as nails pas down through the slots 14-4. their shank portion will cntcr thc apertures 151 and their heads rest upon the projecting points 154') of the s 'n'ing arms. Movably secured to the short tubes 1-16 are three flexible tubes 152. the lower end portions of which are secured in the ends of arms 153, which are pivotally conntv-ted to arms 15st, which, in turn. are pivotally mounted in a common support 155. By means of these arms the tubes 152 may be adjusted in position so that their lower ends will be immediately above the apertures 86 of the press-block 81,

' or so that one of said tubes may be adjusted with its lower cnd directly over the central aperture 85 of the press-bl ock. The top portion of the race-way is spanned by a bar 156 having three apertures therein directly over the respective slots 144, and when only the central race-way is being used, as indicated in Fig. 18, plugs 157 may be inserted in the two outermost apertures 158 of the bar 156 with their lower ends projecting into the outermost slots 1 14: of the race-way, whereby to prevent the descent of nails in said slots. As the bell-crank lever 57-63 is rocked back and forth on the pivot 56, the outer end of the rock-arm 138 will be moved alternately up and down and through the medium of the link 139 this motion, which is a sudden or quick motion, will be imparted to the receptacle 110, thoroughly shaking up the nails therein and causing a greater or less number of them to fall into the slots in the bottom of said receptacle. Mounted on the forked member 131 of the frame be low the bearing of the shaft '29 is a bracket 159 in which are slidably mounted three verticallydisposed plungers 160, which are secured atthcir upper ends in a head 161 which is pivotally mounted intermediate the ends of a lever 162. The lever 162 is pivoted at one end on a bearing mounted on the bracket 159,.as indicated at 163, and at its other end is provided with aroller 16-11 which is mounted in the path of a projection 16.3 carried by some portion of the crank-disk 1:22, such.- as the hub thereof, as indicated by 166, shown in dotted lines in Fig. 1, in full lines in Fig. 2, and on an enlarged scale in Fig. 20. Between the head 161 and the bracket 159 are mounted coil springs 16?, three of said coil springs being shown, and such springs encircling the respective plungers 160. Each of the plungers 160 carries a nail-rcleaser 168 which in operation acts to prcss'the head of a nail past a spring arm 149 so that it may fall through one of the tubes 152 into the press-block S1. The operation of these parts will be included in the description of the general operation of the machine.

Referring to Figs. 1 and 2, 169 indicates a receptacle for containing paste. This re ceptacle is mounted preferably on the righthand side of the machine,-as shown by Fig. 1, and within easy reach of the operator. Mounted in suitable hearings in the sides of the receptacle 169 is a shaft 170, on which is fixedly secured a relatively large Tfillcl' 171 which is adapted to rotate within the receptacle 169 in a direction toward the machine, and having its bottom located reasonably close to the bottom of the receptacle 169 which is suitably shaped to have a portion of its bottom concentric with the periphery of the said roller. The roller'17l is preferably constructed of Wood, but any other suit able material may be employed. 172 indicates a composition roller which is of the same width as the roller 171, and is held in normal engagement with the top of said roller. The roller 172 is mounted at opposite ends in bearings at the upper ends of rods 173 located, respectively, on opposite slidably mounte in suitable bearings and projecting through said bearings into boxes 174, and each rod having at its lower end a collar 175 between which and the upper end of the'boxes is mounted a coil spring 176,

the purpose of this construction being to hold the roller 172 in yielding contact with the roller 171. A series of angle-arms 177 are mounted at the side of the machine proper, and have horizontal extensions 17 8,

the outer ends of which rest upon, or are supported in close proximity to the surface of the roller 171. These arms are located at suitable distances apart throughout the length of said roller, and if desired, the latter may be grooved as indicated by the "ddtted line in Fig. 1, so that the ends-of the arms 178 will be below the periphery of said roller. Mounted in suitable bearings provided on a lateral frame-extension 180, which latter also supports in part the mechanism just above described, are shafts carrying rollers 181 and 182, the latter being considerably smaller than the former, and over which rollers is passed an endless apron 183, the said rollers and apron-being of the same width, or substantially so, as the roller 171, and the smaller roller being located relatively close to the upper art of the said roller 171. The shaft 170 IS suitably connected to a long shaft 18%, which extends to the rear of the machine and is provided at, its end with a sprocket,wheel 185 which is driven from a suitable sprocket wheel on the main driving shaft 27 through the medium of a sprocket chain 186. The shaft 170 has also secured thereon, outside of the receptacle 169, a pulley 187, and the shaft 188 on which the roller 181 is mounted is provided with a pulley-189 over which pulleys is passed a belt 190. Through the driving'mechanism just described the roller 181, and consequently the apron 183, is caused to revolve.

- may be employed for tightening the apron 183.'- As the roller 171 revolves in the re cepta'cle 169 it constantly carries up the paste to the roller 172, which latter is caused to revolve by frictional contact with the former roller. In use the operator places a heel lift on the apron 183 which rapidly discharges it upon the upper surface of the roller 171, which, in turn, carries it underneath the roller 1 72 and discharges it on the grate formed. by the arms 178 where it-may be again picked up by the operator to be placed in position on the heel gage. This construction insures the paste being applied equally to both sides of the lift, and over the entire surface thereof, and

results in great economy in the use of the paste; and owing to the fact that the paste is applied uniformly over the entire surface Any preferred means- 1,122,see

ployed determines the height of the heel.

Referring to the inoperative position of the machine, such as is illustrated in Figs. 1 and 2, as the heel former has assumed such position, the projection 165 on the hub of the crank-disk 122 has engaged the roller at the end of the level-162 and lowered the plunger containing the nail releasers 168 so that one or more nails, according-to the character of heel being built, has been forced past the respective spring arms 1&9 and dropped into the appropriate apertures 86, or the single aperture 85, of the pressblock. The operator now presses on the foot-treadle, raising the rod 35 andthereby lifting the outer end of the arm 40 to carry its stop '12 and its wedge-shaped end 41 out of engagement with the extension 16 of the sliding detent 15. Thelatter is now thrown outward by the spring 50 into the recess 41- 1, thereby locking the cam disk to the constantly-revolving .fly-wheel 32, and causiing the former to revolve.

allowing the end of the arm 40 to fall intothe groove 419-011 the hub of thecain-di'sk.

Assoon as the open: ator has depressed the treadle he releases it As the cam-disk is placed in revolution the cam-groove 34 therein engaging with. the roller 55 causes the outer end of thearm 57 of the bell-crank lever to be moved down? 0 ward and the outer end of' the arm 65 said bell-crank lever to be thrown outward,"

which latter carries the ram 61 with it. In this operation the adjustable plates 114 constituting the heel former will embrace the sides and rear curved portion of the heel lifts which latter will be caused to conform to the shape and configuration previously determined by.,an adjustment of saidplates 114. The engagement of the plates 114 with the liftstis made yielding to prevent a'sudden impact, which operation is effected by the interposition of the spring 71 between the ram and the head 70. (Also the 'heel gage is permitted to yield against the resistance of the coil-spring 100 housed in the plunger-'96. As the heel gage recedes the corners of the heel are permitted to pass between the ends of the adjustableplates 109, thereby insuring the proper conformation of the lifts at the breast of the heel to the desired shape determinedjby the :ad-

block under the As previously explained, it a. heel of pieced justment of the plates 109. 'As the heel formers are thus carried into clamping position by the head 70, the lower end of the rock-arm 78, which is mounted in the end of the ram, will engage the screw 76, thereby causing the press-block 81 to be brought down upon the assembled lifts and temporarily hold them in a compressed relation. As this occurs the rotation of the shaft 29, through engagement of its cranle pin in the slot 12%, will cause the drive-bar 1% to descend so that, in the case of a single nail being driven. the driver 127 will enter the aperture and force the nail 89 therein through the compiled lifts, after which said driver will be withdrawn from the pressaction of the crank-disk.

lifts is to be made. three nails would have been fed into the apertures 86 of the pressblock and instead of a single-driver 127, three drivers would have been mounted in the lower end of the drive-bar 126, and these drivers, in the downward movement of the drive-bar. would have entered the three apertures ot the press-block to drive three nails through the assembled lifts, as shown by Fig. 13. As the driver passes out of the press-block the ram is withdrawn under the continued movement of the camdish. As this backward movement begins the spring will force the pressblock upward out of engagementwith the lifts. The backward movement continues until the edge-shaped end of the arm 40 which is riding in the groove 49 enters behind the extension 4-6 on the sliding 'detent and withdraws the same from engagement with the recess 4% of the fly-wheel, after which the shoulder l2 engages the extension 48 and stops further movement of the cam disk. Ordinarily this stoppage of the cam disk would be accompanied by considerable due to the impact of the extension 46 with the shoulder 42. and the consequent sudden arrest of motion of the cam-disk.- To obviate this i provide the ooil-spring 137, which begins to resist the upward movement of the drive-bar 126 before the engagement o'r' said shoulder and extension. In fact, such engagement does not occur until the crank-pin 123 has passed slightly beyond a dead center. as illustrated in Fig. 17. Thus the maximum compression of the spring is elicited just before the extension lb engages with the shoulder 42, thus cushioning the movement and-aiding in bring} inn, the machine to a stop with scarcely any perceptible iar. At the same time, by arranging the? relative position of the parts so that the cranlcpin 123 will pass slightly beyond a dead center before the machine is brought to a full stop, the coil spring 137 is ready to exert its expansive force to aid in overcoming the inertia of the moving parts when the machine is to be started, thus tending to relieve somewhat the jar and strain of the sudden contact of the wall of the recess 41%. with the end of the sliding detent. As the head reaches the rearmost position, just described, another nail will be dropped in the aperture 85 by the mechanism above described, and such nail will be held in the press-block by the springarm 88 until the press-blocl has again been brought into position over the compiled lifts when the nail 89 will be driven through said litts in the manner described.

The flexible tubes 152 are preferably formed of coiled wire and are readily adjustable by moving the arms 153 to bring their lower ends over the respective apertures 86, or to bring the lower end of any one of said tubes into position over the central aperture 85 when the pressblock is in the rear-most position.

In the rear or return movement of the ram 61 the top of the yoke engages the head 70 to carry the heel-former away from the gage. In this operation the heel-blank would ordinarily be carried back with the heel:t'o1'n1er. To prevent this, I provide the tongue 94, which will hold the blank stationary, and allow the heeLioi-mer to pull away from the same.
